Specification of Letters Patent.

Patented Apr. 1,1919.

Application filed May 29, 1918. Serie1No.237,260.

To all whom it may concern:

Be it known that I, HYMAN LIEBERMAN, a citizen of the United States, residing at Marinette, in the county of Marinette and State of Wisconsin, have invented new and useful Improvements in Direction-Signals, of which the following is a specification.

' The object of the invention is to provide a direction indicatin signal for use in con nection with automo iles and similar vehicles to denote the intention of the driver of the vehicle with regard to turning either to the right or the left or of stopping or reducing his speed for the benefit and instruction of the driver of a following vehicle with the general purpose of preventing or minimizing accidents due to collisions, and in that connection to provide a device for this purpose which can be controlled and operated by the driver of the vehicle without necessitating the removal of his hands from thesteering wheel. or controlling levers or other instrumentalities which are essential to the driving and control of the vehicle.

A further object of the invention is to pro vide an apparatus of this type and for this purpose which may be observed with equal facility in daylight and at night, and be arranged on a vehicle without modification thereof, under such circumstances as to be relatively inconspicuous when not in use or when not adjusted to give an indication to a following driver, and which may be stored or disposed in the vehicle without occupying space which isnecessary for other purpose or is ordinarily appropriated to the use of the occupants of the car.

Further objects and advantages of the invention will appear in the course oi the following description, it being understood that changes in form, proportion and de i tails may be resorted to within the scope of the claims without departing from the spirit of the invention.

In the drawings:-

Figure 1 is a viewof a signaling appa-' ratus arranged in operative position on a car,

Fig. 2 is a diagrammatic view showing the various essential parts of the apparatus in their operative relations,

3 is a detail view of the indicator and the extensible arm or support by which it is carried, and

i Fig. i is a similar view of the operating means for the extension support.

. Essentially the apparatus embodying the invention consists of an indicator which in this instance is represented as a hand 10 having a socket portiop 11 which is con-' nected with an extensible support or arm 12 which is of lazy-tongs construction and which may be mounted in any suitable position. upon or relation with a vehicle body,

preferably within a casing'or housing l stood that in order to provide for display.

of an indicator at either side out the vehicle,

the apparatus as herein described is designed to be employed in duplicate, one of the seats of the combined hand and supporting arm being arranged at each side of the body of the vehicle, and both of which sea-ts may be operated simultaneously when it is desired to indicate to the driver of a following vehicle that it is the intention to duce the speed of motion. I

Connected with the elements of the lazytongs support in any suitable or preferred 'POSltlOIl, is a foldlng spring 14, the tension of which is sufiicient to collapse the support when otherwise released, while connected with an element 15 of support by means stop or reof a rod '16 or its equivalent-is aplunger 17- which preferably constitutes the armature of an electromagnet 18 arranged in circuit through suitable conductors l9'with a battery 20 of the storage or any preferred type.

Also a switch 21 of the push button, treadle or other convenient form should be arranged in the same circuit within convenient reach of the operator to provide for closing the circuit whenever itis desired to extend the indicator for the purposes hereinaboveexplained. a

In the construction illustratedthe plunger or armature 1? is arranged for recipiocatory movement in a casin'g 22; and is provided with an anti friction guiding roller 7 23 for contact therewith in order to insure accuracy of movement toward. and from the magnet in the operation of the device.

Also included in the battery circuit through suitahle branch. conductors A are illuminating meanssuch lamp hnlhs 25 indicator so as to be visible both in front.

and in rear of the vehicle while the latter (which may, if preferred, or for reasons of economy, be omitted) are disposed upon the fingers of the indicator hand.

l om the foregoing description it will be obvious that the actuation of the switch which may be arranged in a position for convenient pressure by the foot of the operator, willresult in an extension of the indicator arm or support by the attraction of the ar r-ature toward the magnet, and if in circuit, as when the device is used at night, the above operation will be accompanied by the energizing of the illuminating device, and as above suggested one or the other of the mechanisms may be actuated to indicate to a driver in. the rear of an intention to turn either to the right or to the left, or by an extension of both devices, it will be obvious to a following driver of an intention to check the speed or stop the machine, so that said following driver may be guided accordingiyr its a means for positively directing the movement of the lazy-tongs support a guide 28 may be arranged in the casing 13 longitudinally of the movement of said support, and the latter may be provided with a carriage 29 to operate in said guide, the same having anti-friction rollers 30 for facilitating such movement by rendering it substantially frictionless, said carriage being connected with the support by means of one of the transverse pivots between the elements of the lazy-tongs construction. This arrangement is particularly clearly shown in Fig. 3 of the drawing.

1 claim:

In a signal device including a movable signal member and an actuating rod; means for moving the rod comprising a casing, an electro-magnet disposed within one end of said casing, said casing being provided with an opening for the passage of said rod, an armature disposed within the other end of said casing and movable longitudinally thereof, said armature being pivotally connected at its center with said rod and positioned for attraction by said magnet, ail-l rollers carried by said armatureat its ends and bearing against the inner walls of said casing.

In testinmny whereof I afiix my signature.

HYMAN LIEBERMAN.
